v2.1.0 — post-evaluation features: core BPN Generator + rolltable provisioning

- SLABPNGenerator: full Blueprint News generation in core — six colour lines
  (blue/green/red/silver/gold/black) with colour-appropriate objectives,
  complications, contacts, codes and reward bands. Creates a two-page journal
  (player Brief + GM-only Dossier) and posts a dispatch card to chat.
  Registered as a GM scene-control tool. (The standalone BPN module targets
  the original zero-engine system; SLA Zero Two is self-contained.)
- Rolltable provisioning: the engine draws 'Ranged/Melee Weapon Critical Fail
  (2-12)' tables by name but fresh worlds had none — all five system tables
  (panic, d66 phys/mental crits, both crit-fails) are now auto-created from
  packs/tables-data.json in any world where they're missing.
